PORTABLE STEAM-.VULCANIZER.

To all whom it may concern: I

Be it known that we, Eocene A. STIER,

and RALPH C. Brno, citizens of the'United States, residing at Dayton, inthe county of Montgomery and State of Ohio, have invented certain newand useful. Improvements in Portable Steam-Vulcanizers; and we dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in portablevulcanizers for repairing pneumatic tires.

The object of the invention is to provide a compact and efiicient deviceof this type, the various details and advantages of whlch will be fiillydescribed in the following specification, and particularly pointed outin the claims. In carrying out this object it has been the aim toprovide for the location of the steam pressure gage at a convenient lacein the vulcanizer where it is protecte from striking against anything inmanipulating the vulcanizer, and to protect said gage also from the heatenerated flaature to which it is desired to call attention is thevulcanizing surface, this is so shaped as to conform to the contour ofthe tire to be mended, both lengthwise and transverse.

. Referring to the accompanying drawings,

'Figurel is a front elevation of the device.

Fig. 2 is a similar view with the front plate removed and partsappearing in section.

Fig. 3 is a section on the line a-a of Fig. 2. The dotted curveindicates the position of the tire relative to the device. Fig. 4 isasection on the line bb of Fig. 2. The dotted curve indicates theposition of the tire. Fig. 5 is a section-on the line cc of Fig. 2; andFig. 6 is a section on the line d-d of Fig. 2.

Throughout the specification and drawings, similar reference charactersindicate corresponding parts. I p

Referrin more particularly to the drawings, it wil be seenthat the body'of the vulcanizer is cast in one integral part.

receives a burner 3. This burner is pro-.

against the lengthwise curve of the vulcanizer, while the dotted curvesin Figs. 4 and 5 indicate the position of the tire against thetransverse curvature of the vulcanizing surface 6. Both curvatures ofthe tire being thus embraced, the manipulation of the vulcanizer isgreatly facilitated. The manner of using this type of'hand vulcanizer iswell understood and requires no further description.

In the rear of the vulcanizing wall 6 and extending from the top 1 andthe inner sides of the walls 2, is a wall 7, which, together with thevulcanizing wall 6, forms the steam chamber 8 for heatin saidvulcanizing wall.

A curved wall 13-jo1ns the rear side of the intermediate wall 7 andprovides a pocket for the reception of .a steam-pressure gage 15 whichfacesthe' operator as he manipulates the implement- Surrounding thesteam gage within the pocket isa supply of suitable heat-insulatingmaterial such as crude asbestos. The side walls 2 are provided withopenings 24 adjacent to the points where the curved wall 13 joins'thefront and side Walls. These openings provide an outlet for the heatgenerated withinlthe device.

Theheat is deflected by the curved wall 13 to these openings and thusthe pocket in which. the steam gageis located, is relieved of anaccumulation of heat. This, in addition to the surrounding wall 13,provides efficient means for protecting the gage from an excessive heat.Also extending from the rear side of thewall 7 are a series of walls 12which lie below the curved wall 13 and provide a series of steam pockets12' which communicate with the steam chamber 8. These steam pockets, itwill be observed, are in the combustion chamber 11 and areheatedtherefrom, the wall 18 concealing t}? gage from the top of thecombustion 'cha her with the steam pockets interposed between the burnerand said wall.

The sides 2 of the body of thevulcanizer are provided with orifices 24' on each side of the gage.These openings form outlets for the products of combustion from theburner chamber, and prevent their accumulation at the gage. The steamchamber 8 is provided with a safety pressure valve :17 which preventsthe pressure of the steam rising to unsafe limits. The safety tube 17'lies parallel with, and close to the top' of the vulcanizer, so that itdoes not encumber the, The, water, from which the steam is generated, isintroduced into the chamber 8 through anopening in the top 1, saidopening being normally closed by a plug 18. The chamber 8 is suppliedwith water to a depth approximately in line with the top of the pockets,12. To ascertainthis point when filling the chamber, one of the sideWalls 2 is provided 'with an op ning 19 at the controlled by a valve 20having a. lateral discharge orifice 21. This valve 20 is opened when thewater is placed in the chamber 7, andv when the A water flows out ofthe.discharge opening 21, it indicates. that sufiicient water has beenplaced in the. steam chamber. I

Extendin from'the side walls 2 are projections 22 y means of which thevulcanizer may be secured to the tire. The vulcanizer may be carried bya handle 23 extending from the cover plate 10. The cover plate 10 isfurther provided with a series of openings 25 which are controlled by aslidable damper 26. The manipulation of this damper allows air to enterthe burner chamber 11, as may be desired, An end of the perforated-slide 26 is turned up to provide a finger piece 27 by which it ismanipulated, guide screws 28 holding it in position, and slots '29permitting its movement. When the burner is inserted in the 4 pocket atthe bottom of the vulcanizer, the

roducts. of combustion pass through the urner'chambe'r 11 aroundthe'pockets 12 and out through the-orifices 24:; When the steam in thechamber- 8 reachesa suiiicient b the pressure temperature, indicatedthereof at the gage, the

' amper openings 25 are placed in communication with the atmosphere,thus allowing suflicient enter the chamber 11 to prevent. thetemperature of the steam rising abovethe vulcanizing point.
